Taking on the stage at Stern's birthday party at the Hammerstein Ballroom on Friday night, Dunham made a toast to the shock jock using the chance to get back at him for previously having called her fat. During her speech, Dunham recalled how Stern apologized after saying she looked like Jonah Hill and how "she was raping his eyes."

"He asked me if I was intimidated because my boyfriend could be getting much hotter ass," Dunham continued. She then hit him with the punch line, "I didn't have the wherewithal to ask Howard if he was intimidated because [his wife] Beth could definitely be with someone... who doesn't look like a cartoon of a Jewish female horse."

However, Dunham took it all in with grace and was humble enough to give Stern some praise for his work and ended the toast by saying, "I do believe that you are a champion of women in the arts."

Stern's party was attended by a slew of celebrities and famous personalities including Robert Downey, Jr., David Letterman, Ben Stiller, Jon Bon Jovi, Sarah Silverman, Barbara Walters, Chelsea Handler and Katie Couric. Plus, the rowdy party included a performance by Steven Tyler with Dave Grohl.
